What's New for System Administrators

IP Quality of Service

IP Quality of Service (IPQoS) is a new feature in the Solaris operating environment. IPQoS enables system administrators to provide different levels of network service to customers and to critical applications. By using IPQoS, the administrator can set up service-level agreements. These agreements provide an ISP's clients with varying levels of service that are based on a price structure. A company could also use IPQoS to prioritize among applications so that critical applications get a higher quality of service than less critical applications. 

For further information, see the IPQoS Administration Guide.

Routing Information Protocol Version 2 (RIPv2)

Solaris system software now supports RIPv2.  

RIPv2 adds Classless Inter-Domain Routing (CIDR) and Variable-Length Subnet Mask (VLSM) extensions to the RIPv1 protocol. MD5 extensions protect routers against intentional misdirection by malicious users. The new in.routed implementation also includes a built-in RDISC implementation.

RIPv2 supports multicast, if the point-to-point links are enabled with multicast. RIPv2 also supports unicast. If you configure a broadcast address by using the /etc/gateways file, then RIPv2 supports broadcast.

For information on how to configure RIPv2, see the in.rdisc(1M), in.routed(1M), and gateways(4) man pages.

Packet Tunneling Over IPv6

This feature enables tunneling over IPv6 for both IPv4 over IPv6 tunnels and IPv6 over IPv6 tunnels. IPv4 packets or IPv6 packets can be encapsulated in IPv6 packets.  

For more information, see the IPv6 Administration Guide.

Memory Placement Optimization (MPO)

The Solaris dispatcher and the virtual memory subsystem have been enhanced to optimize the time that is required for an application to access memory. This enhancement can automatically improve the performance of many applications. This feature is currently implemented to support specific platforms such as the Sun Fire^TM 3800-6800, the Sun Fire 12K, and the Sun Fire 15K.

Dynamic Intimate Shared Memory (DISM) Large Page Support

Large page support is now provided for Dynamic Intimate Shared Memory (DISM). This large page support can increase the performance of applications that are capable of dynamically adjusting shared memory sizes. 

For further information on DISM, see "System Performance Enhancements".

Extended Accounting Subsystem

You can now use extended accounting in conjunction with the flow accounting module for Internet Protocol Quality of Service (IPQoS). For information about IPQoS, see the IPQoS Administration Guide.

For information about the extended accounting feature, see "Extended Accounting" in the System Administration Guide: Resource Management and Network Services.

NIS+ to LDAP Transition Documentation

The "Transitioning From NIS+ to LDAP" appendix has been moved from the System Administration Guide: Naming and Directory Services (FNS and NIS+) to the System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP). And, explanations and examples of various components have been added to the LDAP-related chapters in the System Administration Guide: Naming and Directory Services (DNS, NIS, and LDAP). No new features, however, are documented.
